This is not an argument but rather an invitation for submissions to my blog for some tests I would like Canon users to perform . I reverse engineered Nikon's TTL-BL and would like to attempt the same with Canon flash and share my results with those who may be interested in learning the 'nuts and bolts' of canon's ETTLii flash system .
The tests I've done are all on my TTL-BL blog but if anyone is interested please let me know and I'll suggest some tests to do so we can try to work out the basics of ETTLii .
